We are glad to announce that Geoplast received the BCA Singapore Certification for its Formworks efficiency. BCA is an agency under the Ministry of National Development, championing the development of an excellent building environment for Singapore. ...

This article reviews these sources and proposes a scheme for measuring and quantifying the amounts of metals in their source materials used to bind asphalt used in making roads. The use of bench top EDXRF to characterize binders before blending them into asphalt cements is possible because the metal values are in the 10s – 1000s of ppms and are readily monitored. ...

Municipal wastewater treatment plants are designed to process a calculated range of organic loading in the raw influent. The calculation of this loading is based on characteristics of the plant’s region, such as population and industry type. Organic loading is most often quantified by the concentration of parameters such as Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), ...

Starting with specialization It started with one man and his pickup truck. Tom Banks’ then one-man operation was rooted in specialization. Formed in 2001, Banks Gas Services, Inc. quickly grew from one employee to nearly one hundred. Today the company is a full-fledged gas distribution contractor headquartered in the Pittsburgh area and serving gas distribution companies in ...

The “Shipping, Marine and Ports World” has published in its Dec 2012-Jan 2013 issue, an article written by Dr. Helene Gutman (CTO, Xenemetrix Ltd.). The article presents: The use of EDXRF analytical method systems that enable fleet management to optimize bunkering and machine maintenance. The new sulfur emission regulations for ocean going vessels present a serious challenge ...

The EU Directive 2011/65 / EU is intended to limit the use of hazardous substances in electrical and electronic equipment. Since 22 July 2017 the RoHS regulation is applicable to monitoring and control instruments, including OTT devices and sensors. From this point onwards, we must have a RoHS certification for all devices and sensors. As of 22 July, RoHS is also a compulsory part of the CE ...

The International Water Association water balance is an approach applied worldwide for determining and analysing water losses in water distribution systems (WDS) up to the point of customer metering. Thus, water losses occurring ‘before’ a customer meter are at the expenses of the water utility while water lost or wasted ‘after’ the meter is paid for by the customer. This applies to systems ...

Up to now RoHS wasn’t mandatory for us because we were affected by an exception rule concerning monitoring and control instruments. This exception will end on July 22, 2017 meaning that all products on the market need to be compliant with the RoHS regulations henceforward. If we couldn’t ensure this, we aren’t allowed to further sell and export them. As an environmental ...

The system combines proven DESMI oil spill containment boom with the Boom Guard Monitoring Buoy, an oil pollution monitoring device used to monitor for the presence of oil pollution within the boom containment area. If oil pollution is detected, the buoy transmits an alert via Iridium satellite in real time. The buoy also monitors location and heading and should the ...

This paper describes use of a triple quadrupole GC/MS/MS method using Multiple Reaction Monitoring (MRM) mode for sensitive and selective detection and quantitation of Organochlorine pesticides and PCBs. A database with optimized MRM transitions for all of the OCPs and PCBs, including relative retention times for all components, makes method setup possible within minutes. The use of GC/MS/MS MRM ...

3D Electrical Imaging Objective Study was performed at a Heap Leach Copper Mining site in Chile to determine dry and saturated zones in order to improve the irrigation at the Heap Leach Copper Mining and increase the production of concentrate of Copper. Layout The surveys were ...

Various sources assumed the share of guilt in the fall of the Roman Empire due to the use of the lead pipe, Devonshire colic in the 18th century, poisoning from the addition of lead acetate to wine and pediatric lead poisoning. Not only production but also the use of pottery for centuries caused poisoning among the population. When a piece of pottery covered with lead glaze is not heated enough, ...

Did you know it will cost an estimated $1 trillion over the next 25 years to upgrade the nation’s water system to run more efficiently? While part of the problem is fragile, hundred-year-old water mains, it also falls on property owners to ensure they are doing their part to save water — for both the environment and their wallets. But how? ...

Poor sanitation in rural infrastructure is often associated with high levels of fecal contamination in adjacent surface waters, which presents a community health risk. Although microbial source tracking techniques have been widely applied to identify primary remediation needs in urban and/or recreational waters, use of human-specific markers has been more limited in rural watersheds. This ...

Challenge – Reducing Track Maintenance on Expansive Clay Areas of expansive weak clay subgrades invariably change as a result of seasonal changes in moisture content. For rail track in these areas, the resultant heaving and shrinking causes severe degradation of rail alignment, requiring extensive maintenance. One such area is northern Israel, where the Israel Railway Authority ...

Certification Before a product can earn NSF certification, every aspect of its development is ...

Permanent monitoring of environmental issues demands efficient, accurate, and user-friendly pollutant prediction methods, particularly from operating variables. In this research, the efficiency of multiple polynomial regression in predicting the adsorption capacity of caffeine (q) from an experimental batch mode by multi-walled carbon nanotubes (MWCNTs) was investigated. The MWCNTs were ...

Introduction Sherritt is the largest coal producer in Canada and the largest independent energy producer in Cuba. The company licenses its proprietary technologies and provides metallurgical services to mining and refining operations worldwide. Situation Before msdsBinders the office was full of dusty old binders that sat in the corner and were ...
